4.5 Inch Lift Kit | D/S | C/O V2 | Ford F-250/F-350 Super Duty 4WD (17-22)

Raise your Ford F-250/F-350 Super Duty 4WD (2017–2022) to new heights with Rough Country's 4.5-inch Coilover Suspension Lift Kit — a purposeful D/S C/O V2 upgrade designed for real-world life on and off the trail. This all-inclusive kit delivers bold lift height without sacrificing the ride you rely on for daily driving, towing, and hard work.

What sets this kit apart

• Geometry-first lift: Ultra-durable radius arm drop brackets bolt into factory mounts to preserve factory angles, ensuring predictable handling and tire wear while you climb higher.
• Premium coilover system: Replaces the factory coil/shock setup with a massive 2.5-inch piston, nitrogen-charged Vertex Coilover. This is a monotube design with an external reservoir for increased oil capacity and damping sensitivity, delivering confident control on rough roads and rugged trails.
• Rugged reliability meets performance: Vertex Coilovers provide a robust 8-stage damping adjustment, letting you tailor stiffness for payloads, towing, and off-road terrain — so you can dial in comfort or aggressiveness as needed.
• More fluid, better damping: Rough Country’s 2.5-inch piston design delivers ~56% greater fluid capacity than typical reservoir shocks, resulting in steadier, more consistent damping across speeds and terrain.
• All-in-one upgrade: This kit includes everything you need for a complete transformation—lift components, accompanying monotube shocks, and hardware designed for straightforward installation.

Ride quality, meets gravity-defying height

Despite the impressive 4.5-inch lift, ride quality remains a priority. The combination of geometry-conscious brackets and the Vertex Coilovers maintains a factory-like ride feel, even when you’re cruising on a highway shoulder or carving trails. The external reservoir and monotube design help dissipate heat and keep damping consistent, so you won’t have to compromise comfort for capability.

What you can tow and dial in

Up to 35-inch tires are supported with this kit, opening up substantial ground clearance for off-road adventures while still preserving on-road stability. Use cases range from daily driving and long road trips to weekend rock crawling and farm work. The kit is designed to maintain predictable steering andCV angles, so you’ll notice better approach/departure angles and improved obstacle clearance without a harsh, wallowy feel.

Installation at a glance

The upgrade is ambitious and designed for a precise fit, requiring cutting and drilling for installation. Plan for roughly 6–10 hours to complete the full installation, and you’ll be set for years of high-performance travel. Many owners choose to tackle it at home with the right tools, space, and a methodical approach, but professional installation is also a solid option if you prefer to have it done with lift equipment.

Who this kit is ideal for

• Owners who want dramatic, functional height to accommodate larger tires for off-road adventures or heavy-duty work.
• Drivers who still demand a comfortable, controlled ride on daily commutes and long highway drives.
• Truck enthusiasts who appreciate engineered precision—preserving suspension geometry while upgrading to a robust, high-end coilover setup.

Why this kit outperforms the basics

• Unlike traditional spacer lifts or basic shocks, this kit routes through a dedicated geometry-preserving design that maintains factory alignment characteristics where it matters most.
• The Vertex Coilover system provides superior damping consistency, better heat management, and a broad adjustability range, enabling you to fine-tune for loads, speeds, and terrain.
• With a larger fluid capacity and a monotube architecture, you’ll experience steadier handling and reduced fade on demanding trails or long, fast stretches.

Warranty and peace of mind

Rough Country backs this lift with a limited lifetime replacement warranty against manufacturer defects, giving you confidence in the long-term performance of your upgraded suspension.
